[0041] To enable those skilled in the art to better understand this solution, the technical solutions in the embodiments of this solution will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this solution, not all of them. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this solution.

[0042] The term "comprising" and any other variations thereof in the specification, claims, and accompanying drawings of this invention mean "including but not limited to," and are intended to cover a non-exclusive inclusion, not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish different objects, not to describe a specific order.

[0043] The implementation of this disclosure will be described in detail below with reference to the specific accompanying drawings:

[0044] Figure 1 This is a schematic diagram of a self-service escape system for a car that has fallen into water, provided as an embodiment of this disclosure. (Refer to...) Figure 1 This self-service escape system for cars that have fallen into water includes:

[0045] Safety power supply module, regulation module, water level detection module, trigger switch module, and lighting module;

[0046] The water level detection module comprises a signal generator, an ultrasonic wave transmitting circuit, an ultrasonic wave receiving circuit and a water level grading detection circuit.

[0047] The safety power supply module is connected with the adjusting module; the signal generator is connected with the ultrasonic wave transmitting circuit; the ultrasonic wave receiving circuit is connected with the water level grading detection circuit; and the water level grading detection circuit is connected with the adjusting module.

[0048] The adjusting module is also connected with the trigger switch module and the emergency lighting module.

[0049] The water level detection module is arranged on the vehicle chassis of the automobile.

[0050] The trigger switch module is configured to send the starting signal of the switch to the adjusting module.

[0051] In the embodiment, the safety power supply module is a general power supply unit of the automobile, which usually comprises a generator and can drive the electrical system of the automobile by a belt when the engine is running. When the automobile falls into water, the generator often cannot work, thereby affecting the safe escape of the people in the automobile. The adjusting module in the embodiment can continue to provide energy for the important electrical equipment in the automobile when the generator stops working, and can quickly open the sunroof of the automobile, so that the people in the automobile can safely escape.

[0052] The trigger switch module is a key switch. When the trigger switch module is turned on, an instruction is sent to the adjusting module to start the emergency lighting module, so as to provide sufficient light for the automobile and help the passengers find the escape exit in the dark underwater environment. The adjusting module can also control the working state of the sunroof of the automobile. In an emergency, the adjusting module can instruct the sunroof to be automatically opened to provide an escape channel for the passengers.

[0053] The water level detection module comprises a signal generator, an ultrasonic wave transmitting circuit, an ultrasonic wave receiving circuit and a water level grading detection circuit; the signal generator is connected with the ultrasonic wave transmitting circuit; the ultrasonic wave receiving circuit is connected with the water level grading detection circuit; and the water level grading detection circuit is connected with the adjusting module. The signal generator can generate a square wave signal to drive the ultrasonic wave transmitting circuit to emit an ultrasonic wave signal, and the ultrasonic wave signal is obtained by the ultrasonic wave receiving circuit after passing through a medium. The ultrasonic wave receiving circuit can convert the ultrasonic wave signal into an electrical signal and input the electrical signal to the water level grading detection circuit for signal comparison.

[0054] In this embodiment, when the car is driving safely, the safety power supply module can provide energy for other electrical equipment in the car, and also can provide energy for the backup battery in the adjustment module. When the car falls into water, the safety power supply module often stops working, at this time the backup battery in the adjustment module can continue to work to provide energy for the key escape device. When the water level adjustment module detects that the car falls into water, it sends a signal to the adjustment module, and the adjustment module starts the lighting module according to the instruction. The lighting module can be arranged at positions such as the trunk of the vehicle, the sunroof, etc.

[0055] From the above, first of all, the present disclosure can greatly improve the safety of the vehicle in emergency situations, especially in such extreme environment as the car falling into water. When encountering danger, the personnel in the vehicle can quickly open the sunroof of the vehicle by triggering the switch module and the adjustment module, and starting the emergency escape program.

[0056] Secondly, the emergency lighting module ensures that the personnel in the vehicle can obtain the necessary lighting during the escape process, which greatly improves the success rate and safety of the escape.

[0057] Finally, the trigger switch module in the present disclosure provides two triggering modes of manual and voice, which increases the flexibility and convenience of operation, so that the passengers can start the emergency escape program more quickly in emergency situations. Overall, this car safety system not only improves the escape efficiency, but also significantly enhances the safety guarantee of passengers in emergency situations.

[0058] In one embodiment of the present disclosure, with reference to Figure 2 , the adjustment module comprises:

[0059] The relay, the backup battery, the voltage sensor, the controller, the adjustable motor and the sunroof driving assembly; the outer side of the adjustment module is a waterproof structure for protecting the internal equipment.

[0060] The safety power supply module is connected with the relay, and the relay is connected with the voltage sensor and the backup battery respectively; the voltage sensor is configured to detect the voltage of the backup battery.

[0061] The controller is connected with the adjustable motor respectively, and the adjustable motor is connected with the sunroof driving assembly; the sunroof driving assembly is used for controlling the opening of the sunroof of the vehicle.

[0062] The controller is also connected with the water level detection module, the trigger switch module and the lighting module respectively.

[0063] In the embodiment, the relay is connected with the safety power supply module. When the voltage value of the backup battery collected by the voltage sensor does not reach the rated voltage, the relay is in a closed state, and the safety power supply module supplies power to the adjusting module. When the voltage value of the backup battery collected by the voltage sensor reaches the rated voltage, the voltage sensor sends a control signal to control the relay to be disconnected, and the safety power supply module stops supplying power to the adjusting module.

[0064] The adjusting module is a waterproof structure. When the car is submerged and extinguished, the backup battery can supply power to the voltage sensor, the controller, the adjustable motor and the sunroof driving assembly, so as to ensure that the sunroof of the vehicle can be opened in an emergency.

[0065] The controller is connected with the adjustable motor, and can control the rotating speed of the adjustable motor. When the car is normally driven, the adjustable motor can be set to a low-speed mode to save energy. However, when the car is submerged and extinguished, the controller sets the adjustable motor to a high-speed mode, so that the sunroof driving assembly can quickly open the sunroof to help the people in the car to quickly escape.

[0066] In the embodiment, when the car is submerged, the safety power supply module stops working, and the backup battery in the adjusting module starts working. The people in the car can press the trigger switch on the steering wheel to send a control instruction, and the controller receives the instruction to make the adjustable motor enter the high-speed mode, and then drive the sunroof driving assembly to open the sunroof. At the same time, the controller can also control the lighting device to be turned on to provide safety protection for the people in the car.

[0067] In one embodiment of the present disclosure, with reference to Figure 2 An automobile submersion self-help escape system also includes:

[0068] An alarm module, which is connected with the controller.

[0069] In the embodiment, the alarm module is configured to send an audible and light alarm signal to the outside according to the instruction of the controller. The alarm module can be a high-pitched loudspeaker, a buzzer, a flash lamp and the like. When the car is accidentally submerged, the controller sends an instruction to the alarm module according to the received signal, and the alarm module starts immediately after receiving the instruction of the controller to send an audible and light alarm signal to the outside. The signal can attract the attention of the surrounding people, so that they can quickly notice the submerged car and take rescue action.

[0070] As can be seen from the above, the alarm module can immediately respond to the instruction of the controller, send a conspicuous audible and light alarm signal to the outside, quickly attract the attention of the surrounding people, save valuable escape time for the people in the car, and at the same time guide the rescue personnel to quickly locate, significantly improve the emergency response speed and rescue efficiency of the submersion accident, and effectively enhance the driving safety guarantee.

[0071] In one embodiment of the present disclosure, with reference toFigure 2 The automobile falling into water self-help escape system further comprises:

[0072] a positioning module and a communication module;

[0073] The positioning module is connected with the controller and the communication module respectively, and the communication module is used for connecting with an external terminal; the positioning module is configured to send the position information of the vehicle to the external terminal through the communication module according to the instruction of the controller.

[0074] In the embodiment, the positioning module can obtain the accurate position information of the automobile at present through GPS or other satellite positioning technology, so as to ensure that the position of the vehicle can be accurately determined at any place. The communication module can establish a communication connection with an external terminal (such as a mobile phone, a rescue center, etc.) and transmit data.

[0075] In the embodiment, when the automobile falls into water, the controller will immediately send an instruction to the positioning module to require obtaining the current position information. After receiving the instruction, the positioning module will start the positioning function, and obtain the accurate position of the vehicle through GPS or other positioning technology. Then, the positioning module will deliver the position information to the communication module. After receiving the position information, the communication module will package the position information into a data format suitable for transmission, and establish a connection with an external terminal (such as a mobile phone of the vehicle owner, a rescue center, etc.) through a mobile communication network or satellite communication technology, and then send the position information to the external terminal.

[0076] From the above, it can be concluded that in an emergency, the system can quickly locate the position of the vehicle, and send the accurate position to an external terminal (such as a rescue center or a mobile phone of the vehicle owner) through the communication module, which greatly shortens the rescue response time and improves the emergency handling efficiency of the falling into water accident, so as to gain valuable escape opportunities for the people in the vehicle.

[0077] In one embodiment of the present disclosure, with reference to Figure 3 The trigger switch module comprises:

[0078] a first trigger and a second trigger;

[0079] The first trigger and the second trigger are both connected with the controller in the adjustment module, so as to realize the transmission and control of signals. The first trigger is arranged on the steering wheel of the driver, so as to facilitate the driver to operate quickly in an emergency. The second trigger is arranged at the sunroof position, so as to provide another means for triggering the escape mechanism for other passengers or the driver in a specific situation.

[0080] In the embodiment, the trigger switch module comprises the first trigger and the second trigger, and the two triggers are both connected with the controller in the adjustment module, so as to realize the transmission and control of signals. The first trigger is arranged on the steering wheel of the driver, so as to facilitate the driver to operate quickly in an emergency. The second trigger is arranged at the sunroof position, so as to provide another means for triggering the escape mechanism for other passengers or the driver in a specific situation.

[0081] When the vehicle falls into the water and the water level rises to a certain extent, threatening the safety of the people inside the vehicle, the driver or passenger can choose to operate the first trigger or the second trigger according to the actual situation. Once the trigger is activated, it will immediately send an electrical signal, such as a high-level signal, to the adjustment module. After receiving this signal, the adjustment module will quickly process the signal and trigger the corresponding escape mechanism, such as automatically opening the window, unlocking the door, starting the airbag, etc., to provide an escape channel and time for the people inside the vehicle.

[0082] From the above, it can be concluded that the trigger switch module includes the first trigger of the steering wheel and the second trigger of the sunroof, significantly improving the emergency response flexibility when the car falls into the water. The driver or passenger can quickly choose the trigger mode according to the actual situation and timely start the escape mechanism. This redundant trigger design not only speeds up the escape, but also increases the escape options, providing more survival opportunities for the people inside the vehicle.

[0083] In one embodiment of the present disclosure, with reference to Figure 4 , the ultrasonic receiving circuit comprises:

[0084] ultrasonic receiver X1, amplifier U1, amplifier U2, resistor R1, resistor R2, resistor R3, resistor R4, resistor R5, resistor R6, resistor R7, resistor R8, capacitor C1 and capacitor C2;

[0085] The first end of the ultrasonic receiver X1 is connected to the inverting input terminal of the amplifier U1 through the resistor R1, and the second end of the ultrasonic receiver X1 is grounded. The non-inverting input terminal of the amplifier U1 is grounded through the resistor R2, and the output terminal of the amplifier U1 is connected to the inverting input terminal of the amplifier U1 through the resistor R3;

[0086] The output terminal of the amplifier U1 is also connected to the first end of the resistor R4, and the second end of the resistor R4 is connected to the first end of the capacitor C1 and the first end of the capacitor C2, respectively. The second end of the capacitor C1 is connected to the inverting input terminal of the amplifier U2 and the first end of the resistor R6, respectively.

[0087] The non-inverting input terminal of the amplifier U2 is grounded through the resistor R7, and the non-inverting input terminal of the amplifier U2 is connected to the output terminal of the amplifier U2 through the resistor R8. The output terminal of the amplifier U2 is connected to the second end of the resistor R4 through the resistor R5, and the output terminal of the amplifier U2 is connected to the input terminal of the water level grading detection circuit. The second end of the capacitor C2, the second end of the resistor R6 and the second end of the resistor R7 are all grounded.

[0088] The water level grading detection circuit comprises: resistor R9, variable resistor RP1, diode D1, amplifier U3, resistor R10, variable resistor RP2, diode D2 and amplifier U4;

[0089] The first end of the rheostat RP1 is connected with the first end of the diode D1 and the positive input end of the amplifier U3 respectively, the second end of the rheostat RP1 is connected with VDD, and the third end of the rheostat RP1 and the second end of the diode D1 are grounded; the inverting input end of the amplifier U3 is connected with the output end of the ultrasonic wave receiving circuit through the resistor R9, and the output end of the amplifier U3 is connected with Uout1;

[0090] The first end of the rheostat RP2 is connected with the first end of the diode D2 and the positive input end of the amplifier U4 respectively, the second end of the rheostat RP2 is connected with the second end of the rheostat RP1, and the third end of the rheostat RP2 and the second end of the diode D2 are grounded; the inverting input end of the amplifier U4 is connected with the output end of the ultrasonic wave receiving circuit through the resistor R10, and the output end of the amplifier U4 is connected with Uout2.

[0091] The working principle of the ultrasonic wave receiving circuit is that in the embodiment, the ultrasonic receiver X1 can receive the ultrasonic wave signal emitted by the ultrasonic wave transmitting circuit and convert the ultrasonic wave signal into a corresponding electric signal for output. However, the electric signal output by the ultrasonic receiver X1 is relatively weak and is easily interfered by other signals in the environment, so the amplifier U1 constitutes an amplifying circuit and the amplifier U2 constitutes a filtering circuit, and finally the amplified and filtered signal is sent to the water level grading detection circuit.

[0092] The working principle of the water level grading detection circuit is that the rheostat RP1, the resistor R9 and the amplifier U3 constitute a first grade, and the rheostat RP2, the resistor R10 and the amplifier U4 constitute a second grade. The signals output by the amplifier U1 are respectively sent to the inverting input ends of the amplifiers U3 and U4. The amplifiers U3 and U4 respectively constitute comparison circuits, the rheostat RP1 provides a reference voltage for the non-inverting input end of the amplifier U3, the rheostat RP2 provides a reference voltage for the non-inverting input end of the amplifier U4, and the reference voltage of the non-inverting input end of the amplifier U4 is smaller than that of the non-inverting input end of the amplifier U3.

[0093] When the automobile is normally running, the output voltage of the amplifier U2 is greater than the reference voltages of the non-inverting input ends of the amplifiers U3 and U4, and the amplifiers U3 and U4 both output low levels. When the controller receives two low level signals, it indicates that the vehicle is normally running.

[0094] When the automobile is running in the rain or passing through a water pit, the output voltage of the amplifier U2 becomes smaller. If the output voltage of the amplifier U2 is smaller than the reference voltage of the non-inverting input end of the amplifier U3 and greater than the reference voltage of the non-inverting input end of the amplifier U4, the amplifier U3 outputs a high level and the amplifier U4 outputs a low level. When the controller receives one high level signal and one low level signal, it indicates that the automobile is not submerged, but is only mis-triggered.

[0095] The more water between the ultrasonic wave transmitting circuit and the ultrasonic wave receiving circuit, the smaller the voltage output by the amplifier U2. When the car falls into water, the reference voltage of the in-phase input end of the amplifier U4 and the in-phase input end of the amplifier U3 are both greater than the output voltage of the amplifier U2, so the amplifier U3 and the amplifier U4 both output high level. When the controller receives two high level signals, it indicates that the car falls into water.

[0096] The water level grading detection circuit can divide the signal into different levels according to the preset ultrasonic signal threshold value, and the graded ultrasonic information is output to the controller in the adjusting module. The controller triggers the lighting module, sunroof opening and other operations according to the received ultrasonic information.

[0097] From the above, it can be concluded that such design ensures that the water level detection module can accurately and stably detect whether the car falls into water, avoiding false triggering of the alarm.

[0098] The above examples are only used to illustrate the technical solutions of the present disclosure, but not to limit it; although the present disclosure has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
